Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention is related to method of preparing dairy products containing substantially no glucide or sugar. In this invention, the dairy products mean foods containing a high concentration of milk ingredient such as ice cream and cream puffs.
  • 2. Description of the Related Art
  • Conventionally, the dairy products such as ice cream and cream puffs are well known to have a good taste because of a high concentration of milk ingredient and important foods because of necessary vitamins and good proteins for human being. However, the dairy products are not classified to diet foods because of a lot of sweet content including milk sugar as well as milk fat at the same time.
  • As WHO (World Health Organization) points out, obesity is epidemically widely spread in the world of today and causes increases in diabetes and high blood pressure in addition to heart and vascular diseases. From the nineteen-seventies, the United States of America has promoted a low-fat diet having low calories so as to prevent the obesity, and most people have been practiced, but the population having obesity has been rather increased than before and reached up to the present time.
  • That is, so far, FDA (Food and Drug Administration) has created so-called food pyramid to instruct healthy diets and constructed the pyramid by positioning carbohydrate (60 percents of the entire meals) at the bottom of the pyramid(the most important food), positioning protein there above, and then positioning fat further above, so that the carbohydrate has been mostly emphasized. However, as described above, the population having obesity has been rather increased as the intake of the carbohydrate has been increased and the reduction of caloric value has been progressed. In response to the reversed situations, Dr. Atkins has advocated a low carbohydrate diet for 30 years (reference to Dr. Atkins New Diet Revolution of Robert C. Atkins M. D published by Avon books New York).
  • Recently, except for Dr. Atkins, the people who support the low carbohydrate diet for example Dr. Agatston the writer of South Beach Diet has been increased, and there was a television debates for diet on May, 2003. Since then, in the United States of America, the people who do not eat bread portion of hamburger, pizza or cookies has been rapidly increased. Also, in Japan, the populations having obesity or diabetes and its estimated groups have been rapidly increased, and there was needs to limit the intake of glucide in particular a refined flour or white rice (reference to The South Beach Diet of Dr. Arthur Agatston M.D. published by Rodale).
    • SUMMARY OF THE INVENTION
  • In order to actively suppress the intake of glucide, and enable people to intake dietary fibers (usually deficient), for preventing an adult disease such as obesity, diabetes, hyperlipemia and high blood pressure, it is proposed to use the wheat bran and rice bran effectively which take most parts among food industrial wastes.
  • On the other hand, the dairy products are fitted to a healthy program because the milk ingredient contains materials which can control a variety of bodily function. Recently, it is reporter in US that more the intake of dairy products less the possibility to have high blood pressure. It is recommended for Japanese people who take a lot of Na intake to take dairy products for keeping an ideal intake balance between Ca and Na.
  • Therefore, in order to restrict glucide and fat those ingredient contained even in dairy products become problem, so that those ingredient should be removed therefrom and the skimmed milk has been used for cooking foods. However, elimination of any glucide such as milk sugar in the milk ingredient have not been realized yet although it has been proposed to remove or decompose the glucide and fat in the dairy products.
  • Recently, glucide in the alcoholic drinks is decomposed by a fermenting treatment to get the resulting products containing no glucide. On the contrary, high concentration aqueous solution of milk ingredient cannot be treated by the alcoholic fermentation because milk sugar is a kind of disaccharide which cannot be used for energy of fermentation. Even though the milk sugar can be decomposed to monosaccharide such as glucose, the monosaccharide in high concentration aqueous solution of milk ingredient is not useful for enzyme fermentation because monosaccharide is too thick in high concentration aqueous solution of milk ingredient and tends to be covered by milk protein. Therefore, from the aspect of the invention, it is a first object to provide a method of preparing dairy products containing no glucide, preferably no glucide and no fat.
  • After our sharp researches, it is found that under acidic condition, preferably at pH6 or less, the monosaccharide and the milk protein do not tend to flocculate and keep the solubilized state which can promote decomposition of milk sugar and based on the foundation, the present invention was completed. The present invention is to provide a method of preparing dairy products containing substantially no glucide which comprises; subjecting an aqueous solution of high milk ingredient concentration containing more than 10 wt. % of milk ingredient to a hydrolysis process to decompose milk sugar in the milk ingredient aqueous solution into monosaccharide; subjecting the resulting solution containing monosaccharide under acidic condition for avoiding flocculation to a fermentation process to decrease the content of monosaccharide in the aqueous solution up to substantially zero.
  • In the method of preparing dairy products containing substantially no glucide, it is preferred that the milk ingredient may be made of skimmed milk because the skimmed milk does not contain any fat. In this method, it is preferred that the first hydrolysis process is carried out with glycoside hydrolase such as β-galactosidase family of enzymes which includes lactase involved in the hydrolysis of the disaccharide lactose into constituent galactose and glucose monomers. Further, the second fermentation process is selected from the group consisting of yeast fermentation, alcohol fermentation and yoghurt fermentation. Among them, yeast fermentation is preferred. During the fermentation process, it is preferred that the high concentration milk ingredient aqueous solution under is kept at the acidic condition of pH 6 or less by addition of organic acid selected from the group consisting of lactic acid, citric acid, malic acid and succinic acid, because the acidic condition avoids flocculating and keeps the solubilized state in the high concentration milk ingredient aqueous solution which can promote decomposition of milk sugar.
  • According to the present invention, even if milk ingredient exists at a high concentration, acidic condition can make it solubilized in the aqueous solution and the fermentation can make monosaccharide coming from the milk sugar consumed as energy of fermentation completely if desired by fermentation enzymes without preventing from monosaccharide such as glucose caught into the protein colloid, there can be provided dairy products containing substantially no glucide, preferably containing substantially no glucide and no fat. Typically, there can be provided an ice cream compound containing substantially no glucide which comprises milk ingredient where milk sugar is decomposed to monosaccharide, which is consumed by the above fermentation, a thickening agent and an artificial sweetening agent. The thickening agent may be selected from the group consisting of dry egg white powder, psyllium seed powder, sodium Alginate, Guar gum Pectin, Glucomannan Arabic gum and Xanthan gum. The artificial sweetening agent may be selected from ones used in the cooking food, which are well known in the food field, not including sugar and the like.
  • Further, according to another preferred embodiment, there can is provided a cream compound for cream puffs containing substantially no glucide which comprises milk ingredient where milk sugar is decomposed to monosaccharide, which is consumed by the above fermentation, a thickening agent, a coloring agent and an artificial sweetening agent. The thickening agent may be selected from the group consisting of dry egg white powder, psyllium seed powder and xanthan gum and the coloring agent is selected from the group consisting of turmeric and egg yolk.
  • In this invention, cream compounds do not contain substantially no glucide so that it is preferred corn cup for ice cream and puff shell do not contain no glucide and no fat. Therefore, the corn cup and puff shell had better be prepared from a starting composition comprising bran or soy bean protein as main component added with gluten for binding the main component and milk ingredient processed so as not to contain milk sugar removed by decomposition and yeast fermentation. According to the preferred embodiment, the ice cream containing no glucide and no fat with the corn cup containing no glucide as well as puff shell containing no glucide with cream containing no glucide and no fat can be provided.
  • According to the present invention, the intake of the glucide and fat can be suppressed even if people eat an ice cream or cream puff as usual, the blood sugar level is kept lower.
  • As easily understanding the essence of invention from the explanation, the skill in the art can modify the invention without depart from the scope of the claimed invention by using the inventive composition comprising milk sugar removed by decomposition and fermentation.
    • DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • This invention comprises; 1) a step of subjecting an aqueous solution of high milk ingredient concentration containing more than 10 wt. % of milk ingredient to a hydrolysis process to decompose milk sugar in the milk ingredient aqueous solution into monosaccharide;
    • 2) a step of subjecting the resulting solution containing monosaccharide under acidic condition for avoiding flocculation to a fermentation process to decrease the content of monosaccharide in the aqueous solution up to substantially zero.
  • The starting aqueous solution of milk ingredient may be prepared at a high concentration such as more than 10 wt. % of milk ingredient, preferably by mixing 10 weight portions of skimmed milk added with 30 to 90 weight portion of water, more preferably by mixing 10 weight portions of skimmed milk added with 50 to 70 weight portion of water. Although less than 10 wt. % of milk ingredient can be used, after treatment like dewatering process and so on is necessary and difficult to get a resulting cream-like product.
  • The first hydrolysis process needs glycoside hydrolase such as β-galactosidase family of enzymes such as lactase which is involved in the hydrolysis of the disaccharide lactose into constituent galactose and glucose monomers. The lactase is used at a mixture rate of more than of 1% based on the milk ingredient. The process is carried out at a temperature of 20 to 40 centigrade and the resulting solution is stirred or left uncontrolled for 2 hours. Considering the amount of milk ingredient and so on, the amount of lactase, the decomposing temperature, the decomposing time can be determined and the finishing time can be detected by the usual glucose reaction.
  • The fermenting treatment can be selected from the group consisting of yeast fermentation, alcohol fermentation and yoghurt fermentation according to a kind of the resulting products. The milk sugar is decomposed to monosaccharide galactose and glucose which is useful in fermenting as source of energy. In the fermentation, it is necessary to keep the milk ingredient aqueous solution at less than pH 6 by addition of organic acid such as malic acid and so on in order to solubilize the milk ingredient in the solution, which results in avoiding monosaccharide incorporated by milk protein and promoting fermentation by consumption of monosaccharide. After decomposition, the milk ingredient solution is solubilized by commercially available malic acid solution and will be finished after several hours at 30 centigrade by addition of 1 or 2% of yeast based on the milk ingredient solution. After confirmation of glucose content of less than 1%, the resulting solution is heated to 60 to 100 centigrade to deactivate yeast.
